Beispiele

Im folgenden Codebeispiel wird die Auswirkung des Festlegens von Eigenschaften auf mehrere DataGridViewCellStyle Objekte veranschaulicht. In diesem Beispiel wird die Hintergrundfarbe von Zellen in festgelegt, DataGridView indem die BackColor -Eigenschaft für die DefaultCellStyle -Eigenschaft festgelegt wird. Die Hintergrundfarbe wird in abwechselnden Zeilen überschrieben, da die BackColor -Eigenschaft für die AlternatingRowsDefaultCellStyle -Eigenschaft festgelegt ist. Das Beispiel bestimmt auch das Format der Datumsangaben in der Spalte namens Last Prepared , indem die -Eigenschaft für Format die -Eigenschaft der Spalte DefaultCellStyle festgelegt wird.

Hinweise

Mit DataGridViewCellStyle der -Klasse können Sie Formatinformationen über mehrere DataGridView Zellen, Zeilen, Spalten und Zeilen- oder Spaltenüberschriften hinweg freigeben, wodurch die Arbeitsspeicheranforderungen beim Festlegen von Stileigenschaften für einzelne Zellen vermieden werden. Weitere Informationen zu Klassen, die über eine Eigenschaft vom Typ DataGridViewCellStyle verfügen, und deren Beziehung zueinander finden Sie unter Zellstile im Windows Forms DataGridView-Steuerelement.
